Abstract: An overview of the radio observations during August 2022 is given..
The graphs show both the daily totals (Figure 1) and the hourly numbers (Figure 2) of “all” reflections counted automatically, and of manually counted “overdense” reflections, overdense reflections longer than 10 seconds and longer than 1 minute, as observed here at Kampenhout (BE) on the frequency of our VVS-beacon (49.99 MHz) during the month of August 2022.
The hourly numbers, for echoes shorter than 1 minute, are weighted averages derived from:
Local interference and unidentified noise remained moderate to low for most of the month. Lightning activity was observed on 7 days; the August 16 thunderstorm made observations quite difficult as it was temporarily active near our radio beacon.
Especially in the first half of the month there were several intense solar eruptions causing sometimes considerable noise (Figure 3). Oddly enough, there were only a few faint solar flares on radio waves in the last ten days of the month, notwithstanding the numerous sunspots, prominences, and other eruptions.
The eye-catchers of the month were of course the Perseids, with many long-lasting reflections. After an initial period of increasing activity in the first part of the month, the shower reached its maximum during the nights of 12–13 and 13–14 August. Longer overdense reflections, as usual, came a little later than the underdense.
After the shower’s maximum, meteor activity declined rapidly and remained quite low during the second half of the month, with nonetheless some long reflections.
Over the entire month, 63 reflections longer than 1 minute were registered here. A selection of these and some other interesting reflections are included. (Figures 4 to 23).
In addition to the usual graphs, you will also find the raw counts in cvs-format from which the graphs are derived.
The table contains the following columns: day of the month, hour of the day, day + decimals, solar longitude (epoch J2000), counts of “all” reflections, overdense reflections, reflections longer than 10 seconds and reflections longer than 1 minute, the numbers being the observed reflections of the past hour.
